Pyruvate Carboxylase Is Up-Regulated in Breast Cancer and Essential to Support Growth and Invasion of MDA-MB-231 Cells

PLoS ONE, 2015
Pyruvate carboxylase (PC) is an anaplerotic enzyme that catalyzes the carboxylation of pyruvate to oxaloacetate, which is crucial for replenishing tricarboxylic acid cycle intermediates when they are used for biosynthetic purposes.

Macronutrient and micronutrient profiles of meat types: insights into human health and diet

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Despite considerable advances in global health and nutrition, emerging challenges such as population growth, climate change, and limited natural resources continue to threaten food security. Meat remains an essential component of the human diet, supplying high‐quality proteins, essential amino acids, lipids, vitamins, and minerals necessary ...

Tributyltin Protumorigenic Effects Targeting Prostate Cancer Cell Metabolism, Proliferation, Migration, and Invasion

Environmental Toxicology, Volume 41, Issue 9, Page 709-729, September 2026.
ABSTRACT Prostate cancer (PCa) is an endocrine‐related cancer highly dependent on androgenic signaling. Beyond hormone dependence, extrinsic factors play a significant role in the risk of developing PCa, which raises concern about the influence of environmental compounds such as endocrine‐disrupting chemicals (EDCs). Tributyltin (TBT) is an EDC used in

Pleiotropic Roles of FBXO11 in Tumorigenesis: Implications for Targeted Therapy

Cancer Science, EarlyView.
This complex comprises of scaffold CUL1, SKP1, RBX1 and FBXO11 receptor. The substrate is phosphorylated by specific kinase enzyme and recognized by the substrate recognition domain. FBXO11 targets numerous substrates for ubiquitination and degradation, FBXO11 substrates mainly include Snail, ZEB1, p53, BCL6, CDT2, CIITA, Cdc25a, hnRNPA2B1, SAMD1 and ...

Metabolic responses to pyruvate kinase deletion in lysine producing Corynebacterium glutamicum

Microbial Cell Factories, 2008
Background Pyruvate kinase is an important element in flux control of the intermediate metabolism. It catalyzes the irreversible conversion of phosphoenolpyruvate into pyruvate and is under allosteric control.

The malate–aspartate shuttle supports thermogenic lipid mobilization in brown adipocytes

The FEBS Journal, EarlyView.
Brown fat cells burn lipids within their mitochondria to generate heat. This process involves two energy “shuttles,” one of which is naturally blocked during heat production. We found that the second shuttle (MASh) is not required to generate heat. However, when MASh is disabled, the fatty acids meant for fuel are instead converted back into stored fat.

Caffeylpyruvate hydrolase from the bioluminescent fungus Neonothopanus gardneri is the key recycling enzyme in the fungal bioluminescence pathway

The FEBS Journal, EarlyView.
Caffeic acid is a central metabolite in the fungal bioluminescence pathway. We identified and characterized caffeylpyruvate hydrolase from Neonothopanus gardneri (ngarCPH) and demonstrate its ability to hydrolyze fungal oxyluciferin into caffeic and pyruvic acids, confirming a complete and self‐sustained fungal bioluminescence cycle.

Characterization of the metabolic shift between oxidative and fermentative growth in Saccharomyces cerevisiae by comparative ¹³C flux analysis

Microbial Cell Factories, 2005
Background One of the most fascinating properties of the biotechnologically important organism Saccharomyces cerevisiae is its ability to perform simultaneous respiration and fermentation at high growth rate even under fully aerobic conditions.

Glioma Cells with the IDH1 Mutation Modulate Metabolic Fractional Flux through Pyruvate Carboxylase

PLoS ONE, 2014
Background Over 70% of low-grade gliomas carry a heterozygous R132H mutation in the gene coding for isocitrate dehydrogenase 1 (IDH1). This confers the enzyme with the novel ability to convert α-ketoglutarate to 2-hydroxyglutarate, ultimately leading to ...

CD36‐mediated lipid rewiring in the metabolic adaptation of tumour ecosystems

The FEBS Journal, EarlyView.
Nutrient deprivation drives a lipid‐centric shift in tumour metabolic symbiosis and signalling network. CD36 functions as a bidirectional bridge, transferring fatty acids from stromal donors (adipocytes, CAFs) to the ecosystem tumour‐ and microenvironment‐dependently.
